Experiment 3: perceived size of test and reference arrays at high and low spatial frequency

For the control conditions, the rows of data indicate the proportion of times participants perceived a unbound test array as being larger than a fixed unbound reference array. For the binding ring conditions, the rows of indicate the proportion of times participants perceived a binding ring array as being larger than a fixed unbound reference array. In the high spatial frequency (HSF condition), both arrays were high-pass filtered. In the low spatial frequency (LSF) condition, both arrays were low-passed filtered. Each proportion was calculated from 20 trials.
